( 
)A fuse is an essential, safety critical, element in electrical and electronic device protection. Incorrect replacement can result in personal injury, fire and increase damage to already defective equipment.
Never replace a fuse with a higher amperage rating and in most cases with a lower voltage rating.
You can increase the voltage rating or decrease the amperage rating ( with the possible exception of fuses rated less than 1 Amp) in most applications..... within limits.
Most fuse are identified with the Amperage stated as ___A and the voltage stated as ____V.
Examples: 2A 250V , T6.3A 250V ,7.5A 32V, 10A 125V etc....
Other designators such as SOC, T, AGC, 3AG are size and/or manufacturer's identifiers, I will explain more later.
Several fuse types are: Glass, Ceramic, sand filled, indicating ( springsor coils) among others, I will explain more later.
Voltage ratings are not stated in terms of AC or DC.
